Answer:
-5/7
Step-by-step explanation:
Tip: Dividing by a fraction is the same as multiplying by the reciprocal of the fraction
5x2=−30x−65
Subtract -30x-65 from both sides.
5x2−(−30x−65)=−30x−65−(−30x−65)
5x2+30x+65=0
Use quadratic formula with a=5, b=30, c=65.
x = −30±√−400 / 10
No solution.
Answer:
y = (7/2)x -20
Step-by-step explanation:
The given line is in slope-intercept form, so you can read its slope from the equation.
y = mx + b . . . . . m is the slope; b is the y-intercept
y = -(2/7)x + 9 . . . . . . has slope -2/7
The perpendicular line will have a slope that is the negative reciprocal of this, so will be ...
m = -1/(-2/7) = 7/2
We can use this and the given point to write the equation in point-slope form.
y = m(x -h) +k . . . . . . line with slope m through point (h, k)
We have m = 7/2, (h, k) = (4, -6) so the equation is ...
y = (7/2)(x -4) -6
y = (7/2)x -20
